In the Tang dynasty, celadon and white porcelain were the main names, which were smooth as jade, beautiful and elegant, and were described as "as ice as snow" at that time. Compared with white porcelain, celadon in Tang Dynasty is undoubtedly more famous for its characteristics and artistry. Celadon can be said to be the representative of porcelain in the Tang and Song Dynasties, and its beauty, texture and luster are indeed better than white porcelain. Now, however, celadon is not very common in China. At present, the development of China porcelain is mainly blue and white, famille rose and enamel in Qing Dynasty. Although celadon is not well-known in China, it has taken root in South Korea. Celadon has long been a national treasure and a patent of South Korea.
